Auto merge of #14592 - asajeffrey:util-goodbye, r=mbrubeck

Remove the util crate

<!-- Please describe your changes on the following line: -->

This PR removes the `util` crate.

* Replaced the `spawn_named` and `clamp` functions by appropriate uses of `std::thread::Builder::spawn`, `std::cmp::min` and `std::cmp::max`.
* Moved `opts`, `prefs` and `resource_files` into a new `config` crate.
* Moved `remutex` and `geometry` into their own crates.

- [X] `./mach test-tidy` does not report any errors
- [X] These changes do not require tests because they are refactorings
